System and method for installing smart card applet

Abstract

Disclosed are a system and a method for installing a smart card applet. A response message for an OTA message received from an external remote server is transmitted to form a communication channel based on HTTP (hyper text transfer protocol) between a smart card and the remote server. The applet is installed based on applet installation information received through the communication channel. A large scale applet is installed in a card within a short period of time.

1 . A smart card comprising:
 an SCWS (smart card web server) for establishing a communication channel between a remote server and the smart card based on HTTP by transmitting a message in response to an OTA message transmitted thereto from a remote server and receiving applet installation information from the remote server through the communication channel;   a RAM (remote application management) servlet for receiving identity information included in the applet installation information and identifying the remote server based on the identity information; and   a RAM for receiving an applet installation code included in the applet installation information and installing the applet based on the applet installation code.   
     
     
         2 . The smart card of  claim 1 , wherein the SCWS receives the OTA message in the form of a short message to establish the communication channel. 
     
     
         3 . The smart card of  claim 1 , wherein the SCWS calls the RAM servlet when an applet installation request message based on a URL included in the applet installation information is received from the remote server, and transmits the identity information and the applet installation code to the RAM servlet. 
     
     
         4 . The smart card of  claim 1 , wherein the RAM servlet receives the applet installation code from the SCWS when identification of the remote server has been completed and calls the RAM, and transmit the applet installation code to the RAM. 
     
     
         5 . The smart card of  claim 4 , wherein the SCWS divides the applet installation code based on the size of the applet installation code and transmits the divided applet installation code to the RAM servlet.
